impl DBusMonitor

source

pub fn connect() -> Result<Box<dyn PowerMonitor>, Box<dyn Error>>

Connects and configures a new D-Bus connection to listen for powerd’s PowerSupplyPoll signal.

Trait Implementations§

impl AsRawDescriptor for DBusMonitor

source§

fn as_raw_descriptor(&self) -> RawDescriptor

Returns the underlying raw descriptor. Read more
source§

impl PowerMonitor for DBusMonitor

source§

fn read_message(&mut self) -> Result<Option<PowerData>, Box<dyn Error>>

Returns the newest pending PowerData message, if any. Callers should poll PowerMonitor to determine when messages are available.

source§

impl ReadNotifier for DBusMonitor

source§

fn get_read_notifier(&self) -> &dyn AsRawDescriptor

Gets a descriptor that can be used in EventContext to wait for events to be available (e.g. to avoid receive_events blocking).
